We will be watching the video titled Parts of a Cell, by the Khan Academy on Youtube. Students will create a t-chart to compare prokaryotes to eukaryotes. Students will also record points about the role(s) of various organelles in the cell. Parts of a Cell video
Students will then use computers to examine the website Cells Alive. They will continue to create their own note on the role(s) of organelles in animal and plant cells. They will also create another t-chart comparing differences between plant and animal cells. Cells Alive
See the Homework page for more details on the work done in class on March 2nd.
Cell Structures and Membrane Transport Key Ideas
1. Make sure you have a description of the roles of the organelles studied in both animal and plant cells.
nucleus, nucleolus, cytosol, centrosomes, endoplasmic reticulum (S.E.R, R.E.R.), ribosomes, golgi apparatus, lysosomes, peroxisomes, vacuole, mitochondria, cell membrane, cell wall, cytoskeleton (microtubules), chloroplasts, secretory vesicle
2. What are some differences between prokaryotic and eukaryotic cells. Examples of each?
3. What are some differences between plant and animal cells?
4. Explain the "fluid mosaic model" of cell membranes, by making reference to the structures involved.
5. Read about the various membrane transport mechanisms in the Student Tutorials on Membrane Transport Mechanisms page of the wiki.
i) passive transport (diffusion) (see Khan Academy Video as well)
ii) facilitated diffusion
iii) osmosis (see Khan Academy Video as well)
iv) endocytosis
v) exocytosis
vi) compare passive and active transport, explain active transport pumps like the Na-K pump (see Khan Academy Video as well)

An Osmosis lab similar to what we did (the cytoplasm of the model cell and the fluid around it are reversed compared to what we did in our lab).
